Bard 357-93-E User Manual
THE WALL-MOUNT™ AIR CONDITIONERS - WL (60HZ)
with LEFT SIDE CONTROL PANEL
WL - SERIES Refrigerant 22 60Hz
1.5 to 6 Ton (18,300 to 67,000 Btuh)
Left Side Control Panel
The Bard Wall-Mount Air Conditioner with Left Side Control Panel is
designed to provide complete service access (i.e. compressor, electric heat
strip and electrical controls) when two units are mounted side by side with
minimal space between. The left side unit is the ideal product for
telecommunication and over-the-road medical and communication vans
requiring two wall-mount air conditioners be mounted side by side by using
a WL (left side access) unit and a WA (right side access) unit on the same
building. Factory or field installed accessories are also available to meet
specific job requirements.
Engineered Features
Aluminum Finned Copper Coils:
Grooved tubing and enhanced
louvered fin for maximum heat transfer
and energy efficiency.

Move air quietly. Most models feature
multispeed blower motors providing
airflow adjustment for high and low
static operation. Motor overload
protection is standard on all models.
Air Conditioner Compressor:
Reciprocating compressors with
crankcase heater and dual discharge
muffler are standard on 1.5 and 2 ton
models.
Scroll Compressors eliminate need for
crankcase heater. Standard on 2.5 to
5 ton, and available on 2 ton models.

Ventilation System Packages
Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements.
All units are equipped with a barometric fresh air damper as the standard ventilation package. All ventilation packages can be built-in at the
factory, or field-installed at a later date.
BAROMETRIC FRESH AIR DAMPER - BFAD STANDARD
The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the service
door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the
air inlet openings and to be mixed with the conditioned air. The damper opens during blower operation and
closes when the blower is off. Adjustable blade stops allow different amounts of outside air to be introduced into
the building and can be easily locked closed if required.
Barometric Fresh Air Damper
Motorized Fresh Air Damper
Commercial Room Ventilator
BLANK OFF PLATE - BOP OPTIONAL
A blank off plate is installed on the inside of the service door. It covers the air inlet openings which restricts any
outside air from entering the unit. The blank off plate should be utilized in applications where outside air is not
required to be mixed with the conditioned air.
MOTORIZED FRESH AIR DAMPER - MFAD OPTIONAL
The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation air,
up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed
with the conditioned air. The two position damper can be fully open or closed. The damper blade is powered
open by a 24VAC motor with spring return on power loss. The damper can be controlled by indoor blower
operation or can be field connected to be managed based on building occupancy.
NOTE: The above vent systems are intake only without built-in exhaust capability. Building will likely require
separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Balancing
dampers in the return air grille may be required to achieve specified amount of outdoor air intake.
COMMERCIAL ROOM VENTILATOR - CRV OPTIONAL
The built-in commercial room ventilator is internally mounted behind the service door and allows outside
ventilation air, up to 50% of the total airflow rating of the unit, to be introduced through the air inlet openings.
It includes a built-in exhaust air damper.
The commercial room ventilator (CRV) is a simple and innovative approach to improving the indoor air quality by
providing fresh air intake and exhaust capability through the CRV. The damper can be easily adjusted to control
the amount of fresh air supplied into the building. The CRV can be controlled by indoor blower operation or field
controlled based on room occupancy. Two versions available (except on 1.5 and 2-ton models). The CRV and
CRVS are power open - spring return on power loss, and CRVP is power open and power return. Complies with
ANSI/ASHRAE Standard 62.1 “Ventilation for Acceptable Indoor Air Quality”.
ECONOMIZER - EIFM OPTIONAL
The built-in economizer system is internally mounted behind the service door and allows outdoor air to be
introduced through the air inlet openings. The amount of outdoor air varies in response to the system controls and
settings defined by the end user. It includes a built-in exhaust air damper. The economizer is designed to provide
“free cooling” when outside air conditions are cool and dry enough to satisfy cooling requirements without running
the compressor. This in turn provides lower operating costs, while extending the life of the compressor.
Economizer
Standard Features:
• One Piece Construction - Easy to install with no mechanical linkage adjustment required.
• Exhaust Air Damper - Built in with positive closed position. Provides exhaust air capability to prevent
pressurization of tight buildings.
• Actuator Motor - 24 volt, power open, spring return with built in torque limiting switch.
• Proportioning Type Control - for maximum “free cooling” economy and comfort.
• Moisture Eliminator & Prefilter - permanent, washable aluminum construction
• Enthalpy Control - adjustable to monitor outdoor temperature and humidity.
• Minimum Position Potentiometer - adjustable to control minimum damper blade position for ventilation
purposes.
• Mixed Air Sensor - to monitor outside and return air to automatically modulate damper position.

1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
2 Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes.
3 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical Code (lastest version), Article 310
for power conductor sizing.
Caution: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to note 8 of Table 310
regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in accordance with
the National Electrical Code and all local codes.
